why 4.10s
I recently bought a 4x2 5.7 RCSB Tundra with the sport package. I began to think about why Toyota put 4.10s in the rear end instead of the 4.30s with the sport package. I couldn't think of any reasons. In terms of production cost, I would think it would be cheaper to have just one ring and pinion(4.30) instead of two (4.30s) and (4.10s). In terms of performance, there really isn't that big of a difference between the two different ratios to either effect gas mileage or performance. Any ideas anyone. Also, before I bought my truck I was looking at the Titan, and in all their brochures, they seemed to make sure they made the point that their 5-speed transmission with a rear differential ratio of 2.94 was the equialvent of a 3.73 rear end with a four speed trans. What does our 4.10s equal out to and what does the 4.30s equal out to when compared to a four speed tranny? Thanks,
